The U.S. Department of Transportation, Research and Special Programs Administration, Volpe National Transportation Systems Center (Volpe Center), Acoustics Facility, in support f the Federal Railroad Administration (FRA), is conducting safety research to evaluate the effectiveness of various methods for reducing the number of accidents and resulting casualties at highway-railroad grade crossings. The overall research effort is investigating the use of rail equipment warning devices (e.g., horns, alerting lights, and reflectorization) and the use of track system devices (e.g., signs, signals and lighting systems). As part of this research, the current effort reported here evaluates the detectability of horn systems used as audible warning for motorists at highway-railroad grade crossings, and their resulting impact on the community noise environment.
